Highley Alveley Bridge Refurbishment, Shropshire, United Kingdom
PERI VARIO girder wall formwork
helps bridge two communities
PERI Ltd, were selected to supply VARIO panel formwork for a new pedestrian bridge which links the villages of Highley and Alveley on opposite banks of the River Severn in Shropshire.
Mowlem, later acquired by support services and construction company Carillion, was appointed as main contractor for the new bridge and elected Reinforced Structures as sub-contractor to oversee the formwork and reinforced concrete side of the project.
To minimise working over the river, the main beams for the centre span of the bridge were precast on the Alveley bank and lifted into position by a 1000 t mobile crane.
Mass concrete formers mirroring the arch of the soffit of the bridge were cast on the ground adjacent to the bridge using PERI’s compact panel system. Ply was then fixed to the top of the mass concrete to form the soffit for the beams. The sides of the beams were formed using the PERI VARIO GT 24 system.
The piers and abutments with their ribbed feature surface were cast in one pour using specially shaped circular shutters for the tight radius bullnose at the ends of the piers and the corners of the abutments. The PERI VARIO GT 24 system was used for the straight faces of the piers and abutments.
For speed, reduced on site preparation and to achieve the required high quality finish, all the shutters were pre-assembled at the PERI factory in Rugby and delivered to site ready for use.
“We used the PERI VARIO GT 24 pre-made panel system to form the sides of the beams and for the straight faces of the piers because it is quick, light and easy to use. It proved to be a very effective and highly efficient system. We were also impressed by the technical support and back-up provided by PERI over the course of the project.”
